The numerator of this function given may be factored out as follows,
x² - 2x - 15 = (x - 5)(x + 3)
Given that the expression x - 5 appears in both the numerator and the denominator, we can cancel them and the new function becomes,
f(x) = x + 3
which is continuous at 5.
-2.7 because -3.9 plus 1.2 is -2.7
First make it a fraction, then divide numerator by denominator
12.6 (recurring) %
300 ÷ 10 = 30 = 10%
38 - 30 = 8
8 ÷ 3 = 2.6 (recurring)
10 + 2.6 (recurring) = 12.6 (recurring)
Hope this helps!
